Abstract
Official abstract text for this publication.
A manufacturing method of an optical fiber includes forming an optical fiber by forming a plurality of resin-coating layers around a glass fiber including a core part and a cladding part, and forming a marking on an outermost layer, which is a colored layer having pigment, of the plurality of resin-coating layers by melting or scorching a surface of the outermost layer with a laser.
First claim
Opening claim text (preview).
What is claimed is: 1 . A manufacturing method of an optical fiber, comprising: forming a plurality of resin-coating layers around a glass fiber including a core part and a cladding part; and forming a marking on an outermost layer, which is a colored layer having pigment, of the plurality of resin-coating layers by melting or scorching a surface of the outermost layer with a laser. 2 . The manufacturing method of the optical fiber according to claim 1 , wherein a depth of the marking is equal to or smaller than 3 μm. 3 . The manufacturing method of the optical fiber according to claim 1 , wherein an effective core area of the optical fiber upon transmission of a signal light having a wavelength 1550 nm is equal to or greater than 125 μm 2 . 4 . The manufacturing method of the optical fiber according to claim 2 , wherein an effective core area of the optical fiber upon transmission of a signal light having a wavelength 1550 nm is equal to or greater than 125 μm 2 . 5 . An optical fiber comprising: a glass fiber including a core part and a cladding part: and a plurality of resin-coating layers formed around the glass fiber, wherein a resin layer, which is an outermost layer of the plurality of resin-coating layers, is a colored layer having pigment, and wherein a surface of the colored layer is formed with a marking including a melted portion or a scorched portion. 6 . The optical fiber according to claim 5 , wherein a depth of the marking is equal to or smaller than 3 μm. 7 . The optical fiber according to claim 5 , wherein an effective core area of the optical fiber upon transmission of a signal light having a wavelength 1550 nm is equal to or greater than 125 μm 2 . 8 . The optical fiber according to claim 6 , wherein an effective core area of the optical fiber upon transmission of a signal light having a wavelength 1550 nm is equal to or greater than 125 μm 2 .
